As someone who worked sales at Apple's busiest retail store in college a couple years ago, I can tell you anecdotally that they were far and away the best selling third party headphone, deposited being $180-$300 in price, and employees universally pointing customers towards other brands. (They are far and away the worst in any of the price ranges they sold in, and employees don't get commission)
